SORTING APPARATUS FAOR COINS.

SPECIFICATION forming part of Letters Patent N o. 641,496, dated January16, 1900.

Application filed March 10, 1899. Serial No. 708,587. (No model.)

To @ZZ whom t may concern:

Be it known that I, CHARLES BUSCH, technologist, of 30 Rue Berger,Paris, in the Republic of France, have invented certain new and usefulImprovements in Sorting Apparatus, of which the following is aspecication.

My invention relates to an improved apparatus by which I am able,without any mechanism,to sort round or nearly-round objectssuch, forexample, asV pieces of money.

My apparatus is illustrated -in the accompanying drawings, in which-Figure I is a section on the section-line shown in Fig. 2. Fig. 2 is av-section on the section-line shown in Fig. l. Fig. 3 is aplan view, thetop cover being omitted. Fig. 4is a side View of the front wall ofthesorterpassage. Fig. 5 is a like viewof the rear wall of said passage.Figs. 6 and 7 are vertical transverse sections of two front walls of anold form of passage. Fig. 8is a like view of my improved passage withfront and rear walls and transversely-curved bottom.

I provide a passage or channel Z, curved or inclined longitudinally, asshown in Fig. l, and also inclined transversely, as shown in Figs. 2 and8. The channel has an inlet j large enough to admit the largest objectsto be sorted. Preferably the channel is made of a front or underinclined wall b and a rear or upper wall c, having lugs f, by means ofwhich the sides are secured to the top g of box o just below the cover.In Figs. 4 and 5 lugs f are shown before being bent at right angles tothe channel sides. Walls h c are parallel with each other, and wall bhas an opening increasing in Width, preferably by distinct stepsdiffering in height in accordance with the different sizes or diameterof the objects to be sorted, as indicated at c c2 e3 e4 c5 c6 c7. Thisopening does not extend quite to the bottom of side b, but leaves anarrow iiange b', which forms one side of the transversely-curved bottomor gutter in which the objects to be sorted roll. Longitudinally thegutter curves or inclines downward from inlet j. Preferably the pitch isgreatest near the inlet end, as between and y, and diminishes between yand z, so that the larger objects will not descend too rapidly, but theobjects will issue at about the same speed from all of the parts of theopenings e e2, doc.

Wall c has a opening d extending nearly the length of the opening inwall b.

By cutting away the rear wall forming opening d, extending downward tothe center of the gutter, the coinsrwill be free to fall throughopenings e', doc., without danger of being caught in a manner similar tothat shown in Fig. 7, as they might be were opening d not provided. InFigs. 6 and 7 wall b is shown extended and bent to forma rectangularinclined bottom or gutter of the channel as heretofore used.

It will be seen that with gutters having the form of bottom shown inFigs. 6 and 7 there is danger, if the gutter be too wide, of the coinsor objects rolling down takingtoo great an inclination, as in Fig. 6,and dropping out through the side opening where it is of less width thanthat intended for the coins to issue from. On the other hand, if thegutter be a triiie too narrow in said old form, as in-v dicated in Fig.7, the coin may be caught and held, as shown. My transversely-curvedgut- 'ter compels the coin to take a slightly-inobjects sorted. Thedistance between the center of the tread or bottom of the gutter and theupper stepped edge of the opening in wall b at any point should equalthe diameter of the coin intended to issue at that point plus a triiiesuflicient to allow the coins to tip. I have shown the opening in wall bas continuous, the upper edge being stepped; but it is not essentialthat the open parts of different heights communicate with each other.

In box o is a drawer h, divided into two rows of compartments t" t2 i4716 and i3 5 117. In order to be able to use larger compartments thanwould otherwise be practicable, alternate openings e' c3 c5 e7communicate with the compartments of one row, and openings e264 IOO 2eifle e communicate by chutes k' 7a2 7c3 with the compartments of theother row.

I claiml. 1n a sorting apparatus, a longitudinally and transverselyinclined channel having a transversely-curved bottom along which objectsto be sorted roll and an under Wall b having an opening increasing inWidth from the inlet end, through Which objects fall at points ofcorresponding Width.

2. In a sorting apparatus, a longitudinally and transversely'inclinedchannel having a transversely-curved bottom along which objects to besorted roll and an under Wall b having an opening increasing in Width bysteps from the inlet end, through which objects fall at points ofcorresponding width, in combination with several separate compa-1t mentsin two rows, the sections or steps of the openingin Wall b communicatingalternately with compartments of said rows.

8. A longitudinally and transversely in# clined chute or channel forsortingapparatus having a quick descent near the inlet end and adecreasing descent or inclination toward the lower end, havingatransversely-curved bottom, the under Wall b of the channel having anopening of comparatively small Width near the inlet end and increasingin width toward the other end.

4. A chute or channel for sorting apparatus having in combination a WallZ7 With opening of increasing Width and a Wall c with opening CZopposite the opening in Wall b, said Walls together forming atransversely-curved bottom or gutter.
